You can use spiralized 3D prints as disposable molds for making composite or plaster items like a vase.
I was playing around with TALLY, the extra tall 3D printer and test printed a spiralized vase. I figured why let the print go to waste, and used it as a mold for making a more durable and usable plaster vase.
I happened to have some old Durham's laying around but any plaster based material should be fine.
For a no mess dispensing and easy clump removal, I opted to mix my paster in a ziplock bag. I poured the mix into the vase and rolled it around to coat the entire inside. I did three pours to build up the plaster layer.
A blowtorch and scalpel make quick work of the thin printed mold. Be gentle with the scalpel or you'll end up with scratches like mine.
Notes: 1. You can do this with epoxy too but will likely need a release agent
2. The porous plaster can be sealed by melting in wax or coating the inside with epoxy
